I’M SORRY (information is out-of-date… I’m now updating it slowly).

**2015**

Motivated by the (renormalization) of some classical divergent series in String Theory, e.g.

(see here), I start thinking on the convergence meaning of a class of divergent series, trying to make sense of them without following some of the (standard) approaches as Hardy resummation or Zeta function regularization (e.g. wikipedia). **The main idea was to see if it is possible to define a class of sequences and a equivalence operation, by aggregating terms, such that their “value” is determined by some constant sequence in the same equivalent class.**

In the comments of this post, you see the precise notions and a preliminary result, which is quite open for discussion…
